Metrology Course

Lesson 1 • Measurement Standards Hierarchy

Explains primary, secondary, and working standards and their roles in traceability chains. Students understand how calibration authority flows from national to shop-floor level.

Lesson 2 • Legal and Regulatory Framework

Introduces regulatory metrology concepts, conformity assessment, and the role of accreditation bodies. Students recognize compliance obligations without referencing jurisdiction-specific codes.

Lesson 3 • International System of Units

Covers the seven SI base units, derived units, and prefixes. Students learn to express and convert quantities correctly in any measurement context.

Lesson 4 • Core Metrological Concepts

Defines measurand, quantity, unit, and value with precision. These definitions underpin every subsequent measurement activity in the course.

Lesson 1 • Combined and Expanded Uncertainty

Combines Type A and Type B components using the law of propagation of uncertainty. Students compute expanded uncertainty and coverage factors for reporting.

Lesson 2 • Statistical Foundations for Metrology

Covers mean, variance, standard deviation, and probability distributions relevant to measurement. Provides the statistical toolkit needed for uncertainty evaluation.

Lesson 3 • Uncertainty Evaluation: Type B

Derives uncertainty from non-statistical sources such as calibration certificates and specifications. Students learn to assign probability distributions to each source.

Lesson 4 • Types of Measurement Error

Distinguishes systematic, random, and gross errors with real-world examples. Accurate error classification is the prerequisite for any uncertainty analysis.

Lesson 1 • Instrument Performance Characteristics

Defines accuracy, resolution, repeatability, reproducibility, and linearity for instruments. These parameters guide instrument selection and qualification decisions.

Lesson 2 • Temperature and Pressure Measurement

Introduces thermocouples, RTDs, thermistors, and pressure transducers with their calibration needs. Students evaluate sensor suitability for process conditions.

Lesson 3 • Dimensional Measurement Instruments

Covers calipers, micrometers, height gauges, and coordinate measuring machines. Students match instrument capability to dimensional tolerance requirements.

Lesson 4 • Electrical and Time-Frequency Measurement

Covers multimeters, oscilloscopes, frequency counters, and their traceability requirements. Students recognize how electrical standards underpin modern measurement infrastructure.

Lesson 1 • Calibration Concepts and Objectives

Defines calibration, its distinction from adjustment, and its role in traceability. Students articulate why calibration is a prerequisite for valid measurement results.

Lesson 2 • Calibration Planning and Scheduling

Covers risk-based interval setting, equipment registers, and recall systems. Students design a calibration management plan for a realistic instrument inventory.

Lesson 3 • Calibration Procedure Development

Guides students through writing step-by-step calibration procedures aligned with reference standards. Proper procedure structure ensures repeatability and auditability.

Lesson 4 • Performing and Recording Calibration

Applies procedures to hands-on calibration exercises with data recording. Students practice error correction, as-found and as-left data capture, and labeling.

Lesson 1 • Gauge Repeatability and Reproducibility

Conducts crossed and nested Gauge R&R studies using ANOVA and average-range methods. Students interpret %GRR and number of distinct categories.

Lesson 2 • Bias, Linearity, and Stability Studies

Quantifies systematic offset, variation across the measurement range, and drift over time. Students conduct each study type and assess acceptability criteria.

Lesson 3 • Attribute Measurement System Analysis

Applies kappa statistics and signal detection theory to attribute gauges and visual inspection. Students evaluate inspector agreement and system effectiveness.

Lesson 4 • Introduction to Measurement System Analysis

Defines MSA purpose, key sources of variation, and the AIAG MSA framework. Students understand how gauge variation affects process control decisions.

Lesson 1 • Surface Texture Measurement

Introduces Ra, Rz, and other surface roughness parameters measured by contact profilometers. Students select parameters appropriate to functional surface requirements.

Lesson 2 • Form, Orientation, and Position Measurement

Measures flatness, roundness, cylindricity, parallelism, and true position using appropriate instruments. Students compare results to GD&T tolerance requirements.

Lesson 3 • Optical and Non-Contact Measurement

Surveys laser trackers, structured light scanners, and vision systems for large-scale and complex geometry. Students assess accuracy trade-offs versus contact methods.

Lesson 4 • Geometric Dimensioning and Tolerancing Basics

Interprets GD&T symbols, datums, and tolerance zones from engineering drawings. Correct drawing interpretation is essential before any dimensional measurement.

Lesson 1 • Proficiency Testing and Interlaboratory Comparisons

Covers proficiency testing schemes, z-score interpretation, and interlaboratory comparison design. Students evaluate laboratory performance against peer laboratories.

Lesson 2 • Laboratory Accreditation Requirements

Explains the structure and key clauses of international laboratory competence standards. Students map laboratory activities to accreditation requirements.

Lesson 3 • Method Validation and Verification

Distinguishes method validation from verification and applies fitness-for-purpose criteria. Students validate a measurement method against defined performance parameters.

Lesson 4 • Document and Record Control

Establishes controlled document hierarchies, version management, and record retention rules. Proper documentation is the backbone of laboratory auditability.

Lesson 1 • Conformance Decision Rules

Applies decision rules from international standards to accept or reject measurements near tolerance limits. Students calculate consumer and producer risk under uncertainty.

Lesson 2 • Uncertainty Communication and Risk

Translates technical uncertainty results into clear communication for non-metrologist stakeholders. Students frame measurement risk in business and safety decision contexts.

Lesson 3 • Measurement Uncertainty in Testing

Adapts uncertainty evaluation to chemical, mechanical, and environmental testing contexts. Students build uncertainty budgets for non-calibration measurement tasks.

Lesson 4 • Uncertainty in Multivariate Measurements

Extends uncertainty propagation to vector quantities and correlated input variables. Students handle covariance terms and correlation matrices in uncertainty budgets.
